Beds Question?

Pretty much all of my settlements have their bedding inside an enclosed home with walls and roofs. However, I kinda want to try to make an open air home in Hangman's Alley. My question is basically can I put beds in a shelter that has a roof but no walls on one side without my people getting pissed off about it?

For example, could I put a bed in one of those prefab pieces where there is only a wall on one side?
